New Outlook - Where is the option for the "Search Folders" where we can save searches ?

Agreed. Microsoft developers are idiots for removing this essential tool.

I cannot agree more. The new outlook search folder options are really pathetic and as long an they are not included, the new version is quite useless to manage your e-mail. I really do not understand why Microsoft decided to take out these features, for less advanced users there is always the option to hide this away so they do not need to bother...

Having been using computers since the early 1980s, I have tried not to adopt an "it is the children who are wrong" mindset, so I try to use new products long enough to be very sure it's the product and not my thinking that needs to change.

I did go a very long time with this one, but in the end, I needed to revert back. Being able to click on a folder and see exactly what I need to see at the time I need it without fiddling around with things as simple as constraining to a given folder is just table stakes for me (and probably everyone else who uses Outlook for more than just reading email linearly).

The search issues with Outlook drove me to Thunderbird for a while but the incompatibilities slowly creeping in with O365 and the lack of good calendar support pushed me back. I feel like a prisoner in the Outlook jail sometimes.

Surprised you were able to hang on that long. Took me a very short time to revert to classic Outlook.

I could not agree more. I have basically reverted back to the Classic Outlook. I typically try out new versions of tools for my team but I had to abandon the new version, here. The timeline where we will be forced to switch is quite a long one and I can't afford to lose productivty to manually screwing around with searches all day.
